Examples analyze three-dimensional printing specifications associated with a three-dimensional printing device to determine test angles for a test object and test surfaces corresponding to the test angles for the test object. Examples generate the test object for color calibration for the three-dimensional printing device based at least in part on the test angles and test surfaces that are configured with at least one test color.

1. A non-transitory machine-readable storage medium comprising instructions executable by a processing resource of a computing system to cause the computing system to: receive three-dimensional printing specifications associated with a three-dimensional production object to be printed by a three-dimensional printing device via dispensing a build material and a binding material in a print bed in a layer-wise additive manufacturing process; analyze the three-dimensional printing specifications to determine a plurality of test angles for a test object and a plurality of test surfaces corresponding to the test angles for the test object; generate the test object for color calibration for the three-dimensional printing device that has the plurality of test angles and the plurality of test surfaces, each test surface of the test object configured with at least one test color; analyze the test object to determine a color dependency of the at least one test color of the plurality of test surfaces at the plurality of test angles; determine an amount of printing material associated with the at least one test color; and print the three-dimensional production object with the amount of printing material associated with the at least one test color for surfaces of the three-dimensional production object that are printed at the plurality of test angles that are determined to have the color dependency.
2. The non-transitory machine-readable storage medium of claim 1 , wherein the three-dimensional printing specifications associated with the three-dimensional printing object comprises dimensions of the three-dimensional production object.
3. The non-transitory machine-readable storage medium of claim 1 , wherein the three-dimensional printing specifications associated with the three-dimensional printing object comprises colors of the three-dimensional production object.
4. The non-transitory machine-readable storage medium of claim 1 , wherein the three-dimensional printing specifications associated with the three-dimensional printing object comprises a composition of the build material used to print the three-dimensional production object.
5. The non-transitory machine-readable storage medium of claim 1 , wherein the plurality of test surfaces of the test object are movable to the different test angles.
6. The non-transitory machine-readable storage medium of claim 1 , wherein the plurality of test angles comprise incremental angle values from 0 degrees to 90 degrees.
7. A non-transitory machine-readable storage medium comprising instructions executable by a processing resource of a computing system to cause the computing system to: receive three-dimensional printing specifications to print a test object on a three-dimensional printing device, wherein the three-dimensional printing specifications comprise a size and dimensions of a production object to be printed, test angle information, test surface information, and test color information; analyze the three-dimensional printing specifications to determine a plurality of test angles for the test object and a plurality of test surfaces corresponding to the test angles for the test object; generate the test object for color calibration for the three-dimensional printing device that has the size of the production object, the plurality of test angles and the plurality of test surfaces, each test surface of the test object configured with at least one test color; analyze the test object to determine a color dependency of the at least one test color of the plurality of test surfaces at the plurality of test angles; determine an amount of printing material associated with the at least one test color; and print the production object with the amount of printing material associated with the at least one test color for surfaces of the production object that are printed at the plurality of test angles that are determined to have the color dependency.
8. The non-transitory machine-readable storage medium of claim 7 , wherein the test angle information comprises at least one of: a number of test angles or a relative orientation of the test angles.
9. The non-transitory machine-readable storage medium of claim 7 , wherein the test surface information comprises a size of a test surface.
10. The non-transitory machine-readable storage medium of claim 7 , wherein the test color information comprises at least one of: a number of test colors or an angular orientation of the test colors.
11. The non-transitory machine-readable storage medium of claim 7 , wherein the plurality of test angles comprise incremental angle values from 0 degrees to 180 degrees.
